Description

Technical Field

[0001] This utility model relates to a composite intelligent mixing system for cable materials. Background Technology

[0002] Cables are typically rope-like structures made of several or groups of conductors (at least two conductors per group) twisted together. Each group of conductors is insulated from the others and is often twisted around a central conductor. The entire cable is covered with a highly insulating outer layer. Cables are characterized by internal conductivity and external insulation. Current technology requires the mixing of resin materials during cable production.

[0003] Currently, various devices for material mixing are available on the market. For example, Chinese Patent Publication No. CN108057381A discloses a mixing device for thermal insulation materials, including a crushing section, a conveying section, and a mixing section. The crushing bin contains a first crushing roller and a second crushing roller to crush the raw materials. The first and second crushing rollers, together with a connecting rod and a slider, form an offset crank-slider mechanism. While this device can achieve material crushing and mixing, its mixing effect is not ideal, especially for cable insulation materials that require highly uniform mixing.

[0004] However, existing cable production raw material mixing devices have the following drawbacks: First, the existing mixing devices have low mixing efficiency. During use, resin rubber materials are used to insulate and protect the outer surface of the cable. The existing shaking device is too large, resulting in insufficient shaking amplitude and uneven mixing of the raw materials. Second, the existing cable production raw material mixing devices have weak crushing function. During use, the raw materials need to be crushed before being stirred to make the mixing more uniform and the raw materials more tightly connected during processing. The existing technology requires the crushed raw materials to be transported to the stirring device, resulting in an excessively long overall workflow and low work efficiency.

[0005] Therefore, there is an urgent need for a composite intelligent mixing system that can efficiently crush and uniformly mix cable materials to improve the efficiency and quality of cable production. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing cable production raw material mixing devices, such as low mixing efficiency, uneven mixing, and weak crushing function leading to excessively long workflows and low efficiency. This invention provides a smart composite mixing system for cable materials, achieving efficient and uniform mixing and integrated crushing and stirring functions. This objective is achieved as follows:

[0007] This utility model proposes a composite intelligent mixing system for cable materials, including a mixing chamber, with a crushing chamber connected to the upper part of the mixing chamber. The crushing chamber has a crushing cavity inside, and the upper surface of the crushing chamber has a first feed inlet and a second feed inlet that extend to the crushing cavity. Two crushing components are installed in the crushing cavity, and the crushing components are symmetrically arranged. The mixing chamber has a mixing cavity inside, and a connecting rod is rotatably installed on the upper part of the mixing cavity. A stirring rod is installed at both ends of the connecting rod, and a central rod is installed at the center of the connecting rod. An inclined support is installed inside the mixing cavity. The inclined support includes three sets of inclined blades arranged vertically and vertically at equal intervals. A first protruding roller and a second protruding roller are provided between adjacent inclined blades. One end of the first protruding roller is fixed to the stirring rod, and one end of the second protruding roller is fixed to the central rod.

[0008] Furthermore, the pulverizing assembly includes a second motor unit and pulverizing rollers, the pulverizing rollers being arranged opposite each other with a gap of 0.1-0.5 mm between them, the second motor unit being mounted on the outside of the mixing chamber, and the drive rod of the second motor unit being connected to the pulverizing rollers to drive the pulverizing rollers to rotate.

[0009] Furthermore, the upper surface of the pulverizing chamber is provided with an air supply assembly that communicates with the pulverizing chamber. There are two air supply assemblies, which are symmetrically distributed on the pulverizing chamber. Each air supply assembly includes an air duct, a fan, and a filter screen. The fan is rotatably installed inside the air duct, and a filter screen is installed on the lower side of the fan. The air duct is installed on the pulverizing chamber.

[0010] Furthermore, each group of inclined blades contains 4 blades, the inclination angle of each group of inclined blades is 20 degrees, and the diameter of each group of inclined blades is 50 cm.

[0011] Furthermore, the diameter of the first protruding roller is 2cm, and the length of the first protruding roller is 12cm.

[0012] Furthermore, the diameter of the second protruding roller is 5cm, and the length of the second protruding roller is 6cm.

[0013] Furthermore, the lower part of the mixing tank is provided with a first discharge port and a second discharge port.

[0014] Furthermore, the lower part of the mixing tank is provided with a support platform, and a support column is installed on the lower part of the support platform.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by connecting and installing a crushing box at the top of the mixing box, the integrated design of crushing and mixing functions is realized, which solves the problem of the long working process of crushing raw materials before transporting them to the mixing device in the prior art, and improves work efficiency.

[0016] The air supply assembly further promotes material flow and mixing. Working in conjunction with the inclined blades and protruding rollers, it significantly improves mixing efficiency and uniformity. Compared to existing technologies, this invention achieves a more efficient and uniform mixing effect for cable materials, simplifies the production process, and improves production efficiency.

[0020] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0021] Example 1

[0022] Please refer to Figure 1-2This utility model proposes a composite intelligent mixing system for cable materials, including a mixing chamber 5. A crushing chamber 24 is connected to the upper part of the mixing chamber 5. A crushing chamber 12 is opened inside the crushing chamber 24. A first feed port 1 and a second feed port 10 are provided on the upper surface of the crushing chamber 24, which are connected to the crushing chamber 12. Two crushing components 2 are installed in the crushing chamber 12 and are symmetrically arranged. A mixing chamber 8 is opened inside the mixing chamber 5. A connecting rod 13 is rotatably installed on the upper part of the mixing chamber 8. A stirring rod 6 is installed at both ends of the connecting rod 13. A central rod 15 is installed in the center of the connecting rod 13. An inclined support platform 14 is installed inside the mixing chamber 8. The inclined support platform 14 includes three sets of inclined blades 25 arranged vertically and vertically at equal intervals. A first protruding roller 7 and a second protruding roller 16 are provided between adjacent inclined blades 25. One end of the first protruding roller 7 is fixed to the stirring rod, and one end of the second protruding roller 16 is fixed to the central rod 15.

[0023] Understandably, the crushing assembly 2 includes a second motor unit 3 and crushing rollers 4. The crushing rollers 4 are arranged opposite each other, with a gap of 0.1-0.5 mm between them. The second motor unit 3 is installed on the outside of the mixing chamber 5, and its drive rod is connected to the crushing rollers 4 to drive them to rotate. The gap between the crushing rollers 4 can be adjusted according to the characteristics of the cable material. When processing harder materials, the gap can be adjusted to 0.1 mm to ensure that the material is fully crushed; when processing softer materials, the gap can be adjusted to 0.5 mm to improve crushing efficiency. The connecting rod 13 is driven to rotate by the first motor 11 installed on the upper part of the mixing chamber 5.

[0024] Understandably, the upper surface of the crushing chamber 24 is provided with an air supply assembly 23 that communicates with the crushing chamber 12. Two air supply assemblies 23 are symmetrically distributed on the crushing chamber 24. Each air supply assembly 23 includes an air duct 20, a fan 21, and a filter 22. The fan 21 is rotatably mounted inside the air duct 20, and the filter 22 is installed below the fan 21. The air duct 20 is installed on the crushing chamber 24. The design of the air supply assembly 23 enables a continuous airflow during the crushing process, which helps the material flow and uniform distribution. Simultaneously, the filter 22 prevents impurities from entering the crushing chamber 12, ensuring the purity of the crushed material.

[0025] As is understandable, each set of inclined blades 25 contains 4 blades, each set has a 20-degree inclination angle, and each set has a blade diameter of 50 cm. The design of the inclined blades 25 allows the material to form a spiral upward flow path during mixing, enhancing the mixing effect. The 20-degree inclination angle is the optimal angle verified through multiple experiments, ensuring thorough mixing while preventing excessive splashing.

[0026] Understandably, the diameter of the first protruding roller 7 is 2cm, and its length is 12cm. The first protruding roller 7 is fixed to the stirring rod. As the stirring rod rotates, the first protruding roller 7 can shear and agitate the material, enhancing the mixing effect. The relatively small diameter of the first protruding roller 7 primarily serves for fine stirring, while its longer length ensures that a larger area of ​​material within the stirring chamber 8 can be processed.

[0027] Understandably, the second protruding roller 16 has a diameter of 5 cm and a length of 6 cm. Fixed to the central rod 15, the second protruding roller 16, with its larger diameter, primarily serves to powerfully stir the material, breaking up clumps and promoting uniform dispersion. Although shorter in length, its central location allows for effective processing of the material in the central area of ​​the stirring chamber 8.

[0028] Understandably, the lower part of the mixing tank 5 is equipped with a first discharge port 9 and a second discharge port 18. This dual discharge port design allows the mixed materials to be discharged from different locations as needed, increasing the system's flexibility. The first discharge port 9 and the second discharge port 18 can be connected to different subsequent processing equipment, enabling continuous operation of the production line.

[0029] Understandably, the lower part of the mixing tank 5 is equipped with a support platform 17, and a support column 19 is installed on the lower part of the support platform 17. The design of the support platform 17 and the support column 19 enhances the stability of the entire system, maintaining the stability of the system even at high speeds and reducing the impact of vibration on the mixing quality.

[0030] Optionally, the working process of this intelligent mixing system for composite cable materials is as follows: First, the cable materials to be mixed are put into the crushing chamber 12 from the first feed port 1 and the second feed port 10 respectively. The second motor unit 3 is started to drive the crushing roller 4 to rotate and perform preliminary crushing of the materials. At the same time, the air supply component 23 is started and the airflow generated by the fan 21 helps the materials to be evenly distributed in the crushing chamber 12 and guides the crushed materials into the mixing chamber 8 below.

[0031] Inside the mixing chamber 8, the first motor 11 set connected to the rod 13 is started, driving the mixing rod 6, the central rod 15, and the first and second protruding rollers 7 and 16 fixed on them to rotate together. Under the guidance of the inclined blades 25, the material forms a spiral upward flow path, and is simultaneously subjected to the shearing and stirring action of the first and second protruding rollers 7 and 16, achieving thorough mixing.

[0032] After mixing, the first discharge port 9 or the second discharge port 18 can be opened as needed to discharge the mixed cable material for the next process. The entire process achieves automated and intelligent mixing of cable materials, greatly improving production efficiency and product quality consistency.

[0033] The advantages of this system are: the close combination of crushing and mixing processes enables efficient mixing of cable materials; the special design of the inclined blades 25 and the protruding rollers ensures thorough mixing of materials; the design of dual inlets and dual outlets increases the flexibility and adaptability of the system; and the setting of the air supply component 23 improves the flowability and uniformity of material distribution within the system.

[0034] Example 2

[0035] A composite intelligent mixing system for cable materials includes a mixing chamber 5, a crushing chamber 24 connected to the upper part of the mixing chamber 5, a crushing chamber 12 inside the crushing chamber 24, a first feed inlet 1 and a second feed inlet 10 extending to the crushing chamber 12 on the upper surface of the crushing chamber 24, two crushing components 2 installed in the crushing chamber 12, the crushing components 2 being symmetrically arranged, a mixing chamber 8 inside the mixing chamber 5, a connecting rod 13 rotatably installed on the upper part of the mixing chamber 8, stirring rods 6 installed at both ends of the connecting rod 13, a central rod 15 installed at the center of the connecting rod 13, an inclined support platform 14 installed inside the mixing chamber 8, the inclined support platform 14 including three sets of inclined blades 25 arranged vertically and horizontally at equal intervals, a first protruding roller 7 and a second protruding roller 16 between adjacent inclined blades 25, one end of the first protruding roller 7 being fixed to the stirring rod, and one end of the second protruding roller 16 being fixed to the central rod 15.

[0036] In this embodiment, the pulverizing assembly 2 includes a second motor unit 3 and pulverizing rollers 4. The pulverizing rollers 4 are arranged opposite each other with a gap of 0.3 mm between them. The second motor unit 3 is installed on the outside of the mixing tank 5, and the drive rod of the second motor unit 3 is connected to the pulverizing rollers 4 to drive them to rotate. A gap of 0.3 mm is chosen because this value can achieve a good pulverizing effect for most cable materials, avoiding both over-pulverization which would increase energy consumption and insufficient pulverization.

[0037] In this embodiment, the upper surface of the crushing chamber 24 is provided with an air supply assembly 23 that communicates with the crushing chamber 12. Two air supply assemblies 23 are provided, symmetrically distributed on the crushing chamber 24. Each air supply assembly 23 includes an air duct 20, a fan 21, and a filter screen 22. The fan 21 is rotatably installed inside the air duct 20, and the filter screen 22 is installed below the fan 21. The air duct 20 is installed on the crushing chamber 24. The fan 21 has a power of 200W, which can generate a moderate airflow that promotes material flow without causing fine particles to scatter. The filter screen 22 is made of 100-mesh stainless steel mesh, which can effectively filter impurities in the air.

[0038] In this embodiment, each set of inclined blades 25 contains 4 blades, the inclination angle of each set of inclined blades 25 is 20 degrees, and the diameter of each set of inclined blades 25 is 50 cm. The three sets of inclined blades 25 are equidistantly distributed in the stirring chamber 8, forming three mixing zones. The material is mixed sequentially in these three zones, ensuring thorough mixing.

[0039] In this embodiment, the diameter of the first protruding roller 7 is 2 cm, and the length of the first protruding roller 7 is 12 cm. The first protruding roller 7 is made of wear-resistant alloy material, and its surface has undergone special treatment to enhance its wear resistance and corrosion resistance. The first protruding roller 7 mainly plays a role in shearing and dispersing during the stirring process. Its small diameter and long length allow it to penetrate deep into the material and break up material clumps.

[0040] In this embodiment, the second protruding roller 16 has a diameter of 5 cm and a length of 6 cm. The second protruding roller 16 is also made of wear-resistant alloy material, but its surface is designed with special raised textures to enhance the agitation effect on the material. The second protruding roller 16 mainly functions as a powerful stirrer; its larger diameter generates a stronger agitation force, promoting uniform mixing of the material.

[0041] In this embodiment, the lower part of the mixing tank 5 is provided with a first discharge port 9 and a second discharge port 18. The first discharge port 9 is located at the center of the bottom of the mixing tank 5, with a diameter of 10cm, and is mainly used to discharge uniformly mixed materials; the second discharge port 18 is located on the side of the bottom of the mixing tank 5, with a diameter of 8cm, and is mainly used to empty the system or discharge part of the material for testing when needed.

[0042] In this embodiment, a support platform 17 is provided at the lower part of the mixing tank 5, and a support column 19 is installed at the lower part of the support platform 17. The support platform 17 is made of steel plate with a thickness of 2cm, which has sufficient strength to support the entire system; the support column 19 is made of round steel with a diameter of 8cm and a height of 60cm, which ensures that the system has an appropriate working height for easy operation and maintenance.

[0043] The intelligent mixing system for composite cable materials in this embodiment is particularly suitable for processing cable materials with medium hardness, such as common cable insulation materials like polyvinyl chloride and polyethylene. During system operation, the speed of the second motor unit 3 can be adjusted within the range of 500-1000 rpm, and the rotation speed of the connecting rod 13 can be adjusted within the range of 200-400 rpm to accommodate the mixing requirements of different materials.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
